Effect of Cultivation Factors on Northern Rice Yield and Quality The 10th Report: The Effect of Transplanting Seedling Age on the Yield and Quality of Rice

The experiment of effect of seedling age on rice growth and quality was conducted. The results showed that with the increase of transplanting seedling age, the plant height, leaf age and effective panicle number increased, but the 1000-grian weight decreased. Seedlings with 3.5 or 4.5 leaves were transplanted to obtain the most grains per panicle and yields. When seedlings with older leaf age were transplanted, the processing quality and appearance quality became worse, but the palatability quality increased.
